Phi Sigma Delta (ΦΣΔ), colloquially known as Phi Sig,[1] was an American collegiate fraternity established in 1909 with a predominantly Jewish membership at Columbia University.[2] It eventually opened at least more than sixty chapters. Phi Sigma Delta merged with Zeta Beta Tau in 1970, retiring its original name.[3]
